False , inertia is the tendency of a object to not change their state. I have no idea how the orbit around the sun got mixed up in there ....
Speed =distance/time
3.25=3.00/time
3.25xt=3.00
t=3/3.25
s=0.9s
<span>0.0001 km / year or 10^-5 km/year just take 50 km and divide it by 5 million</span>
Explanation:
Make a table, listing the x and y coordinates of each square's center of gravity and its mass. Multiply the coordinates by the mass, add the results for each x and y, then divide by the total mass.

The x-coordinate of the center of gravity is 15/14 a.
The y-coordinate of the center of gravity is 47/42 a.
